Abstract

A rotating bucket type maize seeding mechanism is characterized in that an elliptic rocker rail groove of a seed taking hopper is arranged on the inner wall at the bottom of a shell of the disc box type seeding mechanism, a sowing turnplate is arranged at the inner side of the inner bottom of the shell of the seeding mechanism, a plurality of turnable seed taking hoppers are installed at the periphery of the inner surface of the sowing turnplate, a sowing baffle is arranged between every two seed taking hoppers and is used for separating the seed taking hoppers, the seed taking hoppers are connected with the sowing turnplate by a rocker which passes through the sowing turnplate along the axial direction, the outer ends of the seed taking hoppers are embedded in the rail groove in the inner wall at the bottom of the shell of the seeding mechanism, and the seed taking hoppers and the rail groove are installed in a matching way by a rocker sleeve of the seed taking hopper; the maize seeding mechanism solves the problem that an external seed filling type seeding mechanism and an internal seed filling type seeding mechanism have low sowing accuracy, and the maize seeding mechanism is applicable to various maize sowing.

Description

Rotary hopper-type corn seeding unit

Technical field

The utility model relates to agricultural seeder machinery accessory field, is the seeding unit on a kind of corn drill specifically.

Background technology

At present the seeding unit on the corn drill mainly contains outer seed filling type and interior seed filling type, and its shortcoming is that the seeding precision is low, every cave quantity inequality of sowing, and the cave distance is in different size.

Summary of the invention

The utility model is for solving outer seed filling type and interior seed filling type seeding unit, and the problem that the seeding precision is low is invented a kind of rotary corn seeding utensil.

The technical solution of the utility model is, a kind of rotary hopper-type corn seeding unit, comprise seeder unit shell and seeder unit shell flap, its special character is, on the inwall of disc cassette type seeder unit shell bottom, have oval-shaped kind of the bucket rocking arm rail groove of getting, bottom inside in the seeder unit shell is equipped with the sowing rotating disk, a plurality of rotating kind of buckets of getting that are peripherally equipped with at sowing rotating disk inner face, each is got all has the sowing baffle plate to be separated by between kind of the bucket, get kind of bucket and connected with the sowing rotating disk by rocking arm, and rocker arm shaft is to passing the sowing rotating disk, the outer end is embedded in the rail groove of seeder unit shell bottom interior wall, cooperates installation by getting kind of a bucket rocking arm cover with the rail groove; The sowing rotating disk cooperates drive outer bottom seeder unit shell to connect by turntable shaft.The rear lower of seeder unit shell sidewall is opened the rectangle sowing port; The bottom of seeder unit shell flap has seed inlet, at seeder unit shell flap inner face seed inlet rear side arcuation holder kind plate is housed, and arc holder kind plate is positioned at the inboard of enclosing sowing port of getting kind of a bucket, sowing baffle plate.Each gets kind of bucket once be able to contain a corn seed.

During work, earlier rotary hopper-type corn seeding unit is fixed on the sower by gusset piece, by the seeder unit shell flap seed inlet seed of packing into, when sowing rotating disk under the transmission of drive, turntable shaft, having driven the corn kind flows along cylindrical wall in seeder unit shell from top to bottom, the seed that flows fills in kind of the bucket of keeping forging ahead, and the position of getting kind of bucket along with the rotation of sowing rotating disk is being changed to a high position by low level in seeder unit shell, gets kind of the seed of bucket outside and drops to leave under the effect of gravity and get kind of a bucket; Getting kind of the elbow of bucket rocking arm with the rotation of sowing rotating disk slides in oval rail groove, oval rail groove is forced to move, and rocking arm makes gets kind of a quarrel and remain up state and hold seed, when getting kind of bucket and running to the outside of arcuation holder kind plate, oval rail groove is stirred rocking arm and is made and get kind of a bucket upset, the seed of pouring out is held by the sowing baffle plate, the corn kind is in the little space that arcuation holder kind plate, sowing baffle plate, seeder unit shell sidewall constitute, and with the sowing dial rotation, just be discharged from when arriving square sowing port place, finish the seeding process one time.

Technique effect of the present utility model is that the employing technique scheme can realize corn seed of a kind of every cave Precision Seeding, and the cave is apart from the uniform supporting utensil of corn drill.

Description of drawings

Fig. 1 is a structural front view of the present utility model, and the accompanying drawing that makes an abstract.

Fig. 2 is the bottom interior wall view of the utility model seeder unit shell.

Fig. 3 is the interior view of the utility model sowing rotating disk.

Fig. 4 is the utility model seeder unit shell flap interior view.

In the drawings, 1 seeder unit shell, 2 sowing rotating disks, 3 rocking arm covers, 4 rail grooves, 5 rocking arms, 6 drives, 7 turntable shafts, 8 sowing ports, 9 seed inlets, 10 are got kind of a bucket, 11 arcuation holder kind plates, 12 sowing baffle plates, 13 disc cassette housing flaps, 14 gusset pieces.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As shown in the figure, on the inwall of disc cassette type seeder unit shell 1 bottom, have oval-shaped kind of the bucket rocking arm rail groove 4 of getting, bottom inside in the seeder unit shell 1 is equipped with sowing rotating disk 2, at a plurality of rotating kind of the buckets 10 of getting of being peripherally equipped with of sowing rotating disk 2 inner faces, each is got all has sowing baffle plate 12 to be separated by between kind of the bucket 10, getting kind bucket 10 is connected with sowing rotating disk 2 by Rocker arm 5; Rocker arm 5 axially passes sowing rotating disk 2; outer end is embedded in the rail groove 4 of seeder unit shell 1 bottom interior wall, overlaps 3 and cooperates installation with rail groove 4 by getting the rocking arm that kind struggles against; Sowing rotating disk 2 cooperates drive 6 outer bottom seeding unit shell 1 body to connect by turntable shaft 7.The rear lower of seeder unit shell 1 sidewall is opened rectangle sowing port 8; The bottom of seeder unit shell flap 13 has seed inlet 9, at seed inlet 9 rear side seeder unit shell flaps 13 inner faces arcuation holder kind plate 11 is housed, and arc holder kind plate 11 is positioned at the inboard of enclosing sowing port 8 of getting kind of a bucket 10, sowing baffle plate 12.

During work, earlier seeder unit shell 1 is fixed on the sower by gusset piece 14, by the seed inlet 9 of seeder unit shell flap 13 seed of packing into, when sowing rotating disk 2 at drive 6, under the transmission of turntable shaft 7, having driven the corn kind flows along the disk wall in seeder unit shell 1 from top to bottom, the seed that flows fills 10 li of kind of the buckets of keeping forging ahead, along with each position of getting kind bucket 10 of rotation of sowing rotating disk 2 is being changed to a high position by low level in seeder unit shell 1, once can only contain a corn seed because each gets kind bucket 10, get kind of the seed of bucket 10 outsides and under the effect of gravity, drop to leave and get kind of a bucket 10; Get kind of the elbow of bucket 10 Rocker arm 5s in 4 li slips of oval rail groove with the rotation of sowing rotating disk 2, oval rail groove 4 is forced to move Rocker arm 5 makes the mouth of getting kind of bucket 10 remains up state hold seed, when getting kind bucket 10 and running to the outside of arcuation holder kind plate 11, oval rail groove 4 is stirred Rocker arm 5 and is made and get 10 upsets of kind of bucket, the seed of pouring out is held by sowing baffle plate 12, the corn kind is in the little space that arcuation holder kind plate 11, sowing baffle plate 12, seeder unit shell 1 sidewall constitute, rotate with sowing rotating disk 2, just be discharged from when arriving square sowing port 8 places, finish the seeding process one time.
